EYEGLASS-MOUNTING.

Specication of Letters Patent.

Application led March 24, 1911, Serial No. 616,600. Renewed August 29, 1912. SeriaI No. 717,791.

To all whom t may concern.'

Be it known that I, HERMAN SILBERT, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements Vin lilyeglass-Mountings, of which the following is a specification.

This invention relates to iinger piece eyeglass mountings and has the object to provide a mounting of this character in which the guards can be readily applied to or removed rom the bridge eitherwith the springs attached or after the springs have rst been removed to permit of easily applying the proper guards to suit different conditions, and it is also an object to permit of conveniently applying and removing the guard and springs themselves and easily and reliably adjusting them to secure the proper tension.

Further objects of the invention are to provide against wabbling or lost motion in the guards and to improve generally the convenience and elliciency of the mounting, both in use and for assembling and repair.

In the accompanying drawings: Figure l is a front view of a pair of eye glasses equipped with my invention. Fig. l2 is a fragmentary top plan view, on an enlarged scale, of one of the guards and adjacent parts of the eye glasses. Fig. 3 is a vertical section of the same. Fig. 4: is a fragmentary perspective view of one end of the bridge and the adjacent clip, wings and spring fastening hook. F ig. 5 is a view similar to Fig. 3 showing a modiication of my invention.

Similar letters of reference indicate corresponding parts throughout the several views.

1 represents the lenses, 2 the bridge or nose piece, 3 the clips or straps arranged at opposite ends of the bridge and each secured to opposite sides of one of the lenses and -l the wings or edge straps arranged on the clips and bearing against the adjacent part of the edge of the lenses.

5, 5 represent the guards which form part of the means for holding the glasses on the nose of the wearer. Each of these guards is constructed in the form of a lever which is pivotally mounted on one end of the bridge and which is provided at one end with a finger piece 7 for manipulating the same and at its other end with a pad or jaw 8 for gripping the nose of the wearer.

My invention concerns the means for pivotally mounting the guards on the bridge and the means for adjusting the tension of the springs. The adaptation of my invention shown in Figs. 1-4: is constructed as followsz-Q represents a vertical tubular pivot wrist or sleeve projecting downwardly from the underside of each guard and rotatably engaging with a pivot or bearing opening 90 in the end of the bridge so that the guard rests on top of the bridge. A screw l0 is provided which serves as part of the means for holding the guard on the bridge and also as part of the means for adjustably securing one of the tension springs of the mounting. The screw threaded shank 11 of this screw engages with an internal screw thread in the pivot wrist while its head 12 is arranged above the guard and provided with an undercut groove or slot 13 which is substantially `Tshaped in cross section. The upper or free end of the screw constitutes a post or projection Xed to the guard lever, but projecting away from the latter and from the support to lie to one side of both and 14: is a spiral spring which surrounds the body of this post 10.

above the guard. One end of the spring is turned inwardly to occupy a central position in the region of the axis of the spring and guard and is moved in an aXial direction to engage in or be disengaged from the interlocking socket 13 prepared for it by the undercut groove of the screw head which opens in and is accessible from an endwise direction while its other end engages with a hook 15 arranged on the adjacent wing of the lens mount and forming a downwardly facing shoulder.

The screw may be turned for securing the desired tension on the spring by inserting a screw driver in the groove 18 of the screw head and then the adjusting screw is held in place by a securing device, preferably in the form of a clamping screw nut'l applied -to the lower end of the threaded shank of the screw and bea-ring against the lower end or' the sleeve 9 so as to compel the guard and screw 10 to turn together. The nut is thus rigidly connected to the guard `lever and arranged closely to the underside of the bridge against which latter it bears so that it prevents the wrist from tipping in the bearing or pivot opening and also prevents the guard from being removed from the bridge under normal conditions.

lf desired the jam nut 16 or equivalent means may be omitted in which case the screw 10 is held solely by friction in its adjusted position on the guard and the hook 15 forms the sole means for preventing the guard from being lifted off the bridge.

Upon turning the screw in the direction for increasing the tension on the spring the outer or free end of the latter is carried under the adjacent hook of the bridge and as the mouth of this hook opens downwardly the free end of the spring is held thereby against lifting, whereby the parts are retained in their normal position. Upon continuing to turn the screw in the direction for releasing the tension on the spring after the tension on the latter has been removed the outer end of the spring is carried from under the hook 15 and the guard is free to be lifted off the bridge provided the nut 16 is not on the screw. When the spring has been thus detached from the hook 15, this spring, the screw and the respective guard while in an assembled condition may be together removed from the bridge and attached thereto without disturbing the relative position of this guard, screw and spring, thereby permitting repairing and adjusting of the guards to be effected quickly and easily, or else the spring may be slipped over the end of the screw or post by disengaging its inner end from the undercut portion of the slotted socket and removed independently either before or after the removal of the guard lever.

If desired, the adjusting screw may be held in position after adjustment by means of a set screw 17 arranged in the lower end of the threaded pivot sleeve and bearing at its upper end against the lower end of the adjusting screw while its head 18 projects along the underside of the bridge and serves aS a stop to prevent the guard from being lifted from the bridge, as shown in Fig. 5.

Owing to the convenience with which this guard can be attached to or removed from the bridge and the facility with which the tension of the spring can be adjusted, it permits the mounting to be readily and quickly adapted to the needs of different persons, thereby saving the time and annoyance frequently incurred when fitting mountings as heretofore constructed.

It will be observed that the post or screw 10 about which the spring` coil is centered is detachable from the guard lever so that the spring may be taken off with it for adjustment, substitution or repair, leaving the guard lever in place on the mounting as it is not necessary to withdraw the tubular pivot portion or wrist 9, even though the securing part 16 be detached. Or, the post, spring and lever may be taken off together and intact so far as their relative positions are concerned, which feature is of advantage, for instance, in that it enables these parts to be interchanged as an entirety, readily assembled, on supports or mountings having bridges of dierent lengths to fit the noses of different wearers. 1n assembling, generally, the guard lever may be applied irst and then the spring and post added while the lever is held by its pivot or wrist in such manner that it cannot become displaced during the process, or else the post and spring may be conveniently applied to the lever first and the assembled parts applied to the bridge by simply adding the nut 16. This is a feature of marked improvement on many of the mountings of the prior art in which a screw or post is used as the key part for securing together the spring, lever and bridge which are meantime held only by the skill of the operator in their relative positions from which the least movement will displace them.
